AbstractDendritic-linear amphiphilic block copolymer, G1-b-PEG, was synthesized through a convergent method. The first generation benzylic dendritic polyether, G1-Cl, was synthesized, and benzylic dendritic polyether, G1-Cl, was used to react with linear monohydroxyl terminated MPEG in alkaline solution via a convergent method. The copolymer was characterized by 1H-NMR. The amphiphilic block copolymer could self-assemble into micelles in aqueous solution, which were used as templates to prepare dispersed silver nanoparticles in water. The morphology and structure of the hybrids were characterized by transmission electron microscopy (TEM) and ultraviolet spectroscopy (UV), 1H-NMR. An absorbance peak at 406 nm appeared after reduction in the UV spectrum. The average diameter of G1-B-PEG /Ag hybrid micelles was 186 nm, and the sliver nanoparticles are stable in aqueous solution due to the stabilization of the dendritic-linear micelles.
